Undertale yellow ost - unused pacifist final boss theme 

It seems that it was early or first version of MOTHER'S LOVE. I can suggest, that they didn't planned three phases for this track, and when they did, they got a reason to completely change structure of track, keeping some ideas from the first version but enhancing them. And truly, it led to good thing, since current MOTHER'S LOVE is a great track, that having a unique vibe.

GOD I love that flowey motif

FRIEND'S LOVE.

It's good, but the one we got was way better. The Your Best Friend part really slaps, though.

Yeah, I found this in the files and wondered why it was never used, it's a banger.

called unforgiving in the files btw
